Abstract
A pin assembly is provided for a plated via of a circuit board. The pin assembly includes a pin sized for insertion into the plated via, and a plurality of expandable elements affixed to the pin. A conductive coating is disposed over the pin and over the plurality of expandable elements. With the pin assembly inserted into the plated via, one or more expandable elements of the plurality of expandable elements can be expanded within the plated via to enhance contact of the pin assembly to a wall of the plated via.

A pin assembly for a plated via of a circuit board, the pin assembly comprising:
- a pin sized for insertion into the plated via;
- a plurality of expandable elements affixed to the pin;
- and
- a conductive coating disposed over the pin and the plurality of expandable elements, wherein with the pin assembly inserted into the plated via, one or more expandable elements of the plurality of expandable elements can be expanded within the plated via to enhance contact of the pin assembly with the plated via.
A method of manufacturing a pin assembly for a plated via of a circuit board, the method comprising:
- providing a pin sized for insertion into the plated via;
- affixing a plurality of expandable elements to the pin;
- and
- applying a conductive coating over the pin and the plurality of expandable elements, wherein the pin assembly is configured for insertion into the plated via and once inserted, one or more expandable elements of the plurality of expandable elements can be expanded within the plated via to enhance contact of the pin assembly with the plated via.
